1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

The scale-up and practical implementation of covalent organic frameworks (COFs) in gas separation remains constrained by intrinsic limitations, including insolubility, infusibility and mismatched pore sizes (>0.8 nm). Drawing inspiration from air-spray principles, herein we develop a facile bottom-up spray-coating strategy for the fabrication of lasagna-like COF membranes for the first time. Theoretical calculations and detailed experiments revealed the core role of spray-coating-induced microdroplet confined assembly, wherein atomized droplets generate spatially confined environments that accelerate molecular ordering and polycondensation. Within these microdroplet-confined spaces, oligo(ethylene glycol) (OEG) side-chains suppress molecular diffusion to enhance crystallization. Such synergy enables dynamic spray cycles to drive COF growth into continuous membranes within 30 minutes. The resulting COF-OEG-4 membrane exhibits outstanding gas separation performance, with an ultrahigh H
